METALLIC ROOFING.

Specification of Letters Patent.

Patented Jan. 18, 1910.

Application filed April 20, 1909. Serial No. 491,189.

To all whom 'it may concern:

Be it known that I, FRANK B. HALE, a citizen of the United States,residing at Fosterville, in the county of Rutherford and State ofTennessee, have invented a new and useful Improvement in MetallicRoofing, of which the following is a specification.

This invention relates to metallic roofing and particularly to sheetiron roofing whether in shingle size or larger sections.

One object of the invention is to produce a section of sheet metalroofing in such form that it may be of universal application; such formthat in covering a roof, the laying of the sections may progress ineither or both directions from the first section laid.

Another object is to so form the edges of thesections that should windget under them it cannot open the lock of the-seams, but will close itmore tightly.

To the attainment of these objects the invention consists in thestructure, formation and combination of features herein set forthsectional recess fold 5 is formed and beyond this at each ed e of thesection an upwardly extending bead fi. while the edges of the sectionare provided with downwardly, and inwardly curvcd locking flanges 7 Itwill be noted that both edges of each section have the same form. Thisprovides, as will be seen in Fig. 2, for laying the sections in eitherdirection from the first section put in place. In Fig. 2 thesection 4 isshown as if laid at some point between the ends of a roof and both edgesnailed down, as by nails 8. A second section, as indicated by dottedlines 9 may then be interlocked with the'first section by. hooking theinwardly curved locking flange 7 into the recess fold 5. Then suchsection would be nailed along its free edge in the same manner as thefirst sectio At the left of Fig. 2 another section, as 10, is indicatedin dotted lines as added to the first section in the manner justdescribed in respect to section 9. This represents that, no matter whereone begins in the length of the roof to lay the sections, the universalform of the section will permit of the laying progressing in either orvboth direct-ions from the section first laid.

In roofing made after this invention, it is not necessary to breakjoints between the sections of succeeding courses, though this may bedone if desired. To provide therefor a wider section is preferably usedand an intermediate head, as 11, formed through the middle thereof, atboth edges of which are formed inwardly'extending recess folds. 12. Intothese folds the locking flanges along the edges of the sheets are slid,as in-- dicated in Fig. 3, wherein two sections, as 4' have been laidand interlocked, as at the point secured by nail 8, and a section 4 ofanother course has had its lower edge lapped onto the upper edge of thefirst course by sliding the corresponding beads and folds of the oneover those of the other.

The heads 6 and 11 may be made of any desired height and form and whenthe roof is laid the nails are all covered and the folds at the sidesthereof may be hammered down if desired. It is obvious that any attemptof the wind to lift the sections will simply draw the locking flangesinto the recess folds more tightly and cannot in any event unlock thejoints without ripping off theentire roof.

The invention claimed is 1. A section of sheet metal roofing provided onboth extreme side edges with identical downwardly and inwardly curvedlooking flanges and, inwardly from said flanges, with identicaloutwardly directed recess folds parallel to the locking flanges andadapted to receive either ofsuch flanges on a corresponding section.

2. A section of sheet metal roofing pro-. vided near its oppositeedges-with identical "raised beads and having identical downwardlyandinwardly curved locking flanges on both extreme edges outside of saidbeads, and having also identical outwardly directed recess folds at theinside of said beads, for the purpose set forth.

3. A sectionof sheet metal roofing provided near its op osite edges withidentical raised beads an having identical downwardly and inwardlycurved locking flanges an inwardly directed recess fold identical onboth extreme edgesoutside of said beads, with the recess folds near theedges of the and having also identical outwardly directsection, for thepurpose set forth.
